Testing Period

Insulation Performance

We filled the bottle with a 2:1 water-to-ice ratio (80 cubes), sealed it, and measured internal temperature every 6 hours over 72 hours using a digital probe thermometer in a controlled 72°F room. Compared results to competitors; RAYMYLO retained below 40°F for 48 hours, losing only 15% ice volume.

Durability and Leak Tests

Dropped from 3 feet onto concrete 10 times (empty and half-full). Shook inverted for 2 minutes post-drop to check leaks. Inspected for dents, seam integrity, and lid seal after 50 open/close cycles. Powder coat scratched minimally vs. Hydro Flask's flawless finish.

Real-World Use

Carried on 10-mile hikes, gym sessions, and commutes; tested sweat, fit in fridges/backpacks, and ease of cleaning with dishwasher cycles. Surveyed 50 users for subjective comfort and longevity feedback.
